Well no external upgrades will help your gun perform better or worse. Theres a reason green berets start with good old m16s with iron sights in basic training. They get to have all the fancy toys after they've completed all of the required training.
Where am I going with this? Well, externals... especially in airsoft... dont enhance the skill of the user at all. They might help with say target acquisition, but if you dont have the underlying skills those $1400 pair of nvg's aren't doing much are they. Just get what you think looks cool on your gun. Start out with a red dot, dont buy magnified optics. They will rarely help in airsoft. A solid red dot will be best bang for your buck.
Finally, please dont buy a power up suppresor. They're garbage
